Letters Patent No. 111,727,.dated February 14, 1871; antedated February 2, 1871.

IMPROVEMENT IN DRAIN-TILES.

The Schedule referred to in these Letters Patent and making part of the same.

Zo all whom it may concern.'

same as ordinarily used.

Tile series of sectionsv forming the drain are composed oi' two completetubes, A and B, and the segmental piece G. This combination forms three separate channels, thus giving a capacity equal to or greater than three times that of the single tube.

The adjacent surfaces of the tubes A and B are ccncave,thus with the segment O forming a circular central channel.

The edges of segment C rest in grooves a and b ou the tubes A and B. The bottom surfaces of said tubes are Hat, which, with the connection formed by the segment C resting in grooves a and l, serves to prevent lateral displacement by pressureon top, thus securing the parts together.

In forming a drain the tubes and segment alternately overlap in joining the sections, as shown by their positions in fig. 1.

An easily-constructed modification of this plan off forming drains may be effected by composing the sections ot' three triangular tubes, the base of one of said tubes resting on the apexes oi' the other two. The base of the upper tube in this case is provided with grooves where it rests upon the lower tubes. Four channels are thus formed .instead of three, as in the accompanying example.

Having thus fully described mysaid invention,

Vhat I claim, and desire to secure by Letters Patent, is-

'lhe tubes A and B, provided respectively with grooves w and b, in combination with the arch O, substantially as and for the purpose set forth.
